Abstract
Grinding and regulating wheels are carried on opposed feed slides on a machine base. A workrest is fixed to the base between the opposed wheels. Wheel dressers are mounted to cross-slides on the base, behind the wheels, independent of the feed slides. CNC dressing occurs through combined transverse motions of feed slide (with wheel) and cross slide (with dresser).
Claims15
A centerless grinding machine, comprising:
- a base;
- a workrest on said base for supporting a workpiece of revolution;
- a grinding wheel slide and grinding wheel mounted on said base for sliding movement along a first feed axis, toward and away from one side of said workrest;
- a regulating wheel slide and regulating wheel mounted on said base for sliding movement along a second feed axis toward and away from an opposite side of said workrest;
- means for moving said grinding wheel slide and regulating wheel slide with respect to said workrest;
- a grinding wheel dresser slide and grinding wheel dresser mounted on said base behind the grinding wheel, independent of said grinding wheel slide;
- and
- a regulating wheel dresser slide and regulating wheel dresser mounted on said base behind the regulating wheel, independent of said regulating wheel slide;
- whereby predetermined movement of said grinding wheel along said first feed axis, away from said workrest, will bring about contact between said grinding wheel and said grinding wheel dresser, and whereby predetermined movement of said regulating wheel along said second feed axis, away from said workrest, will bring about contact between said regulating wheel and said regulating wheel dresser.
